闽南福建柏人工林生长动态的研究

Studies on the Growth Dynamics of Fokienia hodginsii Plantation in South Fujian

通过对１９６０～１９９５ 年间营造的福建柏人工纯林的调查， 对福建柏的胸径、树高、材积、形数和树干生长规律进行分析， 分别建立生长过程模型。结果表明， 福建柏树高速生期比胸径早， 幼龄阶段材积增长缓慢，１２ａ 后材积生长加速； 随树龄的增大， 胸径形数呈反向生长， 树形不断向圆锥体靠近。

The results indicated that the fast growing period of Fokienia hodginsii height was earlier than that of dbh;the volume increase was slow in the young stage and the volume growth accelerated twelve years later;and with the increase of the tree age,the dbh class number assumed the reverse growth and the tree form continually neared a cylinder.
